Abstract

A fire service elevator includes an elevator cage with a cage roof, wherein the elevator cage is at least partly supported and driven by at least one support device, wherein the elevator cage is looped under by the at least one support device, wherein the elevator cage has a protective element, which is arranged at least partly around the at least one support means and disposed substantially on the cage roof. The protective element screens the at least one support device relative to a central region of the cage roof so that extinguishing water falling onto the cage roof in the case of fire is substantially prevented from wetting the at least one support device.
